CHATTANOOGA, Tenn. (AP) — The Nuclear Regulatory Commission has cited the Tennessee Valley Authority for purchasing thousands of parts not documented as nuclear-grade quality. The parts are for the Watts Bar Nuclear Plant in Spring City, Tenn.
TVA must now hire a contractor to look into at least 6,200 shipments of different parts. Some have already been installed and some date to 1995.
It was also unclear Thursday whether some of the parts might also have gone to the Sequoyah Nuclear Plant in Soddy-Daisy, Tenn., and the Browns Ferry Nuclear Plant near Athens, Ala.
TVA officials who met Thursday with regulators in Atlanta said their engineers didn't notice a 1995 requirement change on testing of parts from vendors who weren't nuclear-certified.
TVA says its plants are safe.
